IMPROVEMENT IN CARRlAGE-WHEEL HUBS.

Specification forming part of Letters Patent No. 121.694, dated December5, 1871.

To all 'whom it may concern:

Be it known that I, HOLLAND E. VIOK, ofAlliance, in the county of Starkand State of Ohio,

have invented a certain new and Improved Oarriage-WVheel Hub 5 and I dohereby declare that the following is a full, clear, and completedescription thereof, reference being had to the accompanying drawingmaking part of the same.

Figure 1 is a side view of the hub. Fig. 2 is a longitudinal transversesection. Figs. 3, 4, and 5 are detached sections.

Like letters of reference refer to like parts in the several views.

The nature of this invention relates to a carriage-wheel hub and theobject thereof is to combine a wooden core or hub, in which the spokesare secured by mortise-joints, with a metal shell,

or a pair of thimbles, constituting a shell, and

which thimbles are secured to the core and connected to each other bymeans of the axle-box,

having on its posterior end a chambered head and on the other anut.

A further and more full description of the hub is as follows In thedrawing, Fig. 2, A represents the wooden core or hub referred to, and Bthe mortises in which the tenons of the spokes are inserted. To each endof said core is fitted a thimble, O D, Fig. 1, in the edge of which areformed square notches E, Fig. 3, corresponding in shape to the mortisein the core, and in depth equal to about one-half the length of saidmortises, and with which they are arranged in corelation, as shown inFig. 1. In the chamber of each thimble, near the outer ends, is acircular flange or rim, 0 d, Fig. 2', which extends from and forms apart of each thimble. In said Fig. 1 it will be seen that the notchesform the sides and ends of about half the length of the mortises, andwhich add to the depth of said mortises by their flange or web F, raisedabove the surface of the thimble and extending on each side to the depthof the notches. From the base or bottom of the notches project radiallugs G, and also lugs G from the projections formed by the contiguoussides of the notches, as shown in the drawing, in which it will beseenthat a lug stands at each end of the mortises B, and whereby theshoulders or base of the spokes are braced and supported laterally. Therelative position of the two sections or thimbles G D to each other andto the core A, and also their adjustment to the mortises B, is shown inFig. 1. The thimble thus formed and adjusted to the core makessupplementary extensions to the depth of the mortises in the core forholding and strengthening the connection of the spoke with the hub. H,Fig. 2, is the axleboX, of which Fig. 5 is a detached view. On one endof said box is cut a male screw, I, whereas on the opposite end is ahollow head, J.

The above-described hub is put together as follows: The spokes aretitted to the wooden core by tenons in the usual way. The thimbles G Dare then placed on over the ends of the core or hub, one on each sideofthe spokes, against which they are clamped or drawn tightly by meansof the axle-box, which is inserted in the hub, as shown in Fig. 2, inwhich it will be seen that the head J fits closely in the end of thethimble O, seen at J, Fig. 2, on the opposite end of which is screwed anut, A, which, on being screwed tightly against the flange or rim (1 ofthe thimble D, draws the two thimbles toward each other over the hub A,thereby clamping the base of the spokes be tween the lugs G and G, whichare thereby strongly braced in a lateral direction, and supportedcircumterentially by the flanges or webs F and the edge of the lugs. Asaforesaid, the mortises are so arranged as to be in and out or staggeredin relation to each other, thereby causing the end of the mortise to beterminated about midway that of the next in order. By this arrangementof the mortises additional strength is given to the sides of thespokes-by means of the lugs G, thus adding materially to the strength ofthe wheel. A wheel thus constructed is neat, strong, and durable, andwhich embraces the advantages of the wooden hub without its greatthickness, and the strength of the iron without much additional weight.The hub is of small diameter, and, therefore, has the appearance oflightness, but which, however, is strong, as the lugs give great bracingstrength at the insertion of the spokes in the hub.

In practice the wheel is set up as follows: The shells or collars (J Dare first placed on over the core and secured thereto by the axle-boxand nut A, above described. The spokes are then fitted and driven intothe mortises of the core, which is prevented from cracking by beingbound tightly by the (-ollars or shells. In this way the tenons 1 Etherein, lugs G G, and webs F, and provided of the spokes are made totit nnn-h tighter than I with a rim or flange, 0 (1,in combination withthe when driven in before the collars Zll'l' put on.
